Wireless Hart


Communication Protocol has served as the world’s leading process
communication technology for smart instruments since 1989. Today, more
than 30 million HART transmitters are installed and in service

Industry suppliers are manufacturing and shipping HART products in
record numbers—75% of the smart transmitters installed are HART-enabled.
More HART products are installed in more plants around the world than
any other. No other communication protocol comes close.

Wireless technology allows users to access the vast amount of unused
information stranded in these installed HART smart transmitters— 85% of
the installed HART transmitters. It also provides a cost-effective,
simple and reliable way to deploy new points of measurement and control
without the wiring costs.
